You can not hurt the system by trying different combinations. It just won't start up.
- usually there are three pins and only two are connected. This means that there are only two ways to connect it. It may be that both ways work. Try one and if it doesn't work then flip it 180 degrees and try the other way. Push buttons and power switches don't care about color. They are non-intelligent, on-off devices.

Will a NVIDIA GeForce gt 610 graphics processor work on a Dell Dimension 2400 PC Desktop


YES, Zian it will work....BUT,....................

1) It is a PCI graphics card, and uses a PCI expansion slot.

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=2898922&CatId=319

The Dell Dimension 2400 Desktop PC's motherboard, has three long white PCI slots,

http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/techov.htm#1105465

http://www.ebay.com/itm/Dell-Dimension-2400-Desktop-Motherboard-System-Main-Board-F5949-K5148-G1548-/190750417467?pt=Motherboards&hash=item2c699c623b

http://en.wikipedia.org/wiki/Conventional_PCI

If one of those long white PCI slots is open, you can use a PCI graphics card.

Concerned that the graphics card uses DDR3 graphics memory, and your computer only uses DDR Sdram ram memory?

Don't be.

The graphics card has it's own processor (Graphics Processing Unit), and graphics memory.
It runs independent of the system resources; the Processor and Ram Memory.

http://en.wikipedia.org/wiki/GPU

The concern is the Power Supply.
Original power supply's maximum rated Wattage is either 200 Watts, or 250 Watts.

The above graphics card requires a minimum system requirement/power supply requirement; of 300 Watts.

I would recommend replacing the Power Supply.
(Especially with it's age, if it is still the same one)

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1389575&CatId=1078

ONE thing though..............
Watch the 20-pin ATX main power cable connector, and the wires in it. Be sure they are in the standard place setup.

Check the pinout, and color code of the wires,

1) Dell Dimension 2400 desktop computer, 20-pin ATX main power cable connector pinout,

http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/techov.htm#1105612

2) STANDARD 20-pin ATX main cable connector pinout, and color code of wires; as set by JEDEC,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

[Be aware that the ATX main power cable, and connector, you get with a new power supply; such as the above, will have a 20 =4-pin ATX main power cable connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

Use the 20-pin connector, tie the 4-pin power cable up out of the way]

For a time period Dell was making the motherboard's main power cable connector - Proprietary.
Meaning they has that motherboard connector wire pinout changed.
Colors of wires were in a different place, than the standard setup by JEDEC.

Orange wires are 3.3 Volts (DC)
Red wires are 5 Volts (DC)
Yellow wires are 12 Volts (DC)
Black wires are Ground wires.

Guess what happens if a 12 Volt Yellow wire, is plugged into where a Black Ground wire is supposed to be?

ZZZZZZzzzzt! Motherboard fries, processor fries, ram memory fries, and graphics card. (If used)

Check the color code of the wires, in the 20-pin ATX main power cable's CONNECTOR, for the Dimension 2400's power supply.

For additional questions please post in a Comment.

Mcp61sm-am motherboard manuel needed


Ya know Acer owns Gateway now,

http://support.gateway.com/s//MOTHERBD/Shared/4006233R/4006233Rnv.shtml

A) Power Supply to motherboard cabling;

http://www.ebay.com/itm/ECS-MCP61SM-AM-V-1-0A-SOCKET-AM2-AMD-MOTHERBOARD-uATX-/290606277901

Scroll down to the motherboard top view photo.

Product Views > Hardware Details

1) 24-pin ATX main power cable. (S - Main Power Connector)

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

[Note color of connectors does NOT matter ]

Note the Lock on the side of the main power cable's connector, and the matching Tab on the motherboard connector. When properly plugged in, the hooked end of the Lock will be over the Tab, on the motherboard connector.

In the photo of the motherboard shown on the Ebay link, this connector is on the Right side of the motherboard, next to the blue IDE (PATA) connector.

2) 4-pin ATX +12 Volt power cable; (F - Auxiliary 12V ATX Connector)

General example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

In the motherboard photo; Small square 4-socket hole connector, to the Bottom/Left corner of the Processor socket.

This power cable's connector also has a Lock, and the motherboard connector has a Tab.

That's all the power cables that go to the motherboard.

B) With 2 SATA headers (Connectors) on the motherboard, and one IDE (PATA) connector, it suggests to me that this motherboard is set up to use a SATA harddrive.

This is a general example of a SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note that it has 15 contact pins, and between it, and the SATA data cable connector, it is the larger of the two.
There is a Lock tab on the connector that you depress, to install, or remove the cable.

You can use a SATA optical drive (CD/DVD drive), or an IDE (PATA) optical drive.
An IDE (PATA) optical drive uses a standard 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

[ Misnomered as a 'Molex' power cable. Molex was the first to make the power cable's connector. Name stuck, kind of like calling an open-end wrench a Crescent wrench ]

A SATA data cable is used for the SATA harddrive. The connector end that goes to the Harddrive, is usually a 90 degree bent elbow.
The straight end plugs into the motherboard,

General example of a SATA data cable, and it's corresponding connector on the motherboard,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the L-shape in the inside of the SATA data cable's connector, and the L-shape on the motherboard connector. They line up.
The SATA power cable also has this L-shape.

In Hardware Details click on -> Q - SATA Connectors
The Bottom one, or one closest to the outside edge of the motherboard, is SATA1.

Although it isn't marked on the motherboard, or at least not visible in this photo, SATA 4 is. Look at the top where a SATA 4 connector would be.
The SATA harddrive should be plugged into the SATA1 header.
(Connector)

HOWEVER, the beauty of SATA is that it does NOT matter, which SATA header on the motherboard, you plug the SATA harddrive into.

BIOS will find it.

(Supposed to be SATA harddrive to SATA1, and a SATA optical drive to SATA2)
In the motherboard photo on Ebay, they are Orange in color, and under the blue IDE (PATA) connector.

C) Going from Hardware Details and the Ebay motherboard photo;

B - CPU Fan 1 Connector, is where the Processor fan plugs in.
In the motherboard photo, there are 7 cylindrical Electrolytic Capacitors in a row, to the left of the processor socket.

This connector is located immediately above the top capacitor, near the outside edge of the motherboard. (Brown in color)

E - Floppy Disk Connector, is above the white 24-pin ATX main power cable's connector, and the blue IDE (PATA) connector. It is Yellowish in color. (34 pins)

G - System Fan Connector, is white in color, has 3 contact pins, and is located under the white, square 4-pin ATX +12 Volt power cable connector. This is where the computer case fan plugs in.

I - PCI Express x16 Connector, is Orange in color, and below the processor socket. It has PCI Express silkscreened on the motherboard immediately below it.
This where a graphics card, and ONLY a graphics card, is installed.

J - PCI Express x1 Connector, is white in color, and immediately below the orange PCI Express x16 connector.
This is NOT used for a graphics card.

Whatever you can use in a PCI slot, except a graphics card, can be used in this slot; -> Provided it is a PCI Express x1 card.
(Ethernet Card, Sound Card, etc)

L - CD-in Connector is where the audio cable from the Main (Primary) optical drive goes to.
Ya got me on this one. I know it's located real close to the Realtek audio chipset, and I think that is to the left of the orange PCI Express x16 slot.

M - Front Audio Connector, is where the front audio (Sound) ports, of the Front Panel connect to.
Green in color, and located under the bottom white long PCI slot, and near the outside edge of the motherboard.

N - Clear CMOS Jumper is self explanatory. It is located under the finned Heatsink, (Looks like a meat tenderizer), of the Southbridge chip.
(Which is located under the Ram Memory slots)

O - USB Connectors are Yellow in color, and located under the finned Heatsink of the Southbridge chip, and towards the outside edge of the motherboard. (Or also located under the Ram Memory slots)

P - Front Panel Connector, is located at the Bottom/Right corner of the motherboard, close to the 'Buzzer'. (Buzzer is used for BIOS Beep Codes) PANEL1

4 pins on the Left side, 5 pins on the Right side.
The pins on the Left side are numbered EVEN.
The pins on the Right side are numbered ODD.

Starting on the Bottom of the Left side going Up;
Pins 2, 4, 6, 8, and 10.

Starting on the Bottom of the Right side going Up;
Pins 1, 3, 5, and 7

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch. IF a Reset switch is used.

C) Pin 9 is Not Connected. Used by the factory.

D) Pins 2 and 4 are for the Power On LED. (Light)
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

More to follow.

Burnt connector inside dell inspiron, first connector at motherboard (after power box) Can I fix it?? If so, can u help??


LOVE your user name!

I'll try to guide you the best that I can.
Sorry, first connector after Power Supply does me no good.

Let's look at a basic schematic of the motherboard for a Dell Inspiron 530s Desktop PC,

Dell Support > Inspiron 530s Desktop PC > Dell Inspiron 530s Series Owners Manual,

http://support.dell.com/support/edocs/systems/insp530s/en/OM/HTML/index.htm

I would like you to click on - Removing and Installing Parts
In the left column click on - System Board Components
{System Board = Motherboard }

This is a basic view of the motherboard with No hardware components installed.
It is also how the motherboard sits in your computer.

This is a pictorial view of the motherboard,

http://www.amazon.com/Dell-Motherboard-Inspiron-Systems-Compatible/dp/B003CO0WQS

Now, compare the Dell Support motherboard illustration, to the pictorial.
Looking to the far right in the illustration, the first connector is marked with the number 8.

On the pictorial it is the rectangular Black connector at the bottom/middle. (Next to the rectangular White connector)

This connector is for a Floppy Drive.
Is this the connector in question?

Is it the white rectangular connector next to it?
This connector is for the main power cable coming from the Power Supply.
In the illustration is is marked by the number 7.

This is a basic example, of the power cable coming from the Power Supply (power box), that connects to the white connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

{Note* Color of the main power cable's connector does not matter. It can be any color }

IF this connector on the motherboard is burnt, you may wish to stop.
Electricity has more than likely fried the entire motherboard. May also include the Processor, Ram Memory, Harddrive, and a graphics card, if installed.

I know. I'm a 'ray of sunshine'.

How could this connector be burnt?
Four ways I know of;

1) Lightning storm, or power outage. Also could have happened if the power utility company was doing some changes in the power lines, utility pole transformer, etc.
(No. The utility company cannot be held responsible. I don't agree with that)

2) Power cable was not plugged in tightly. Lock on side was not locked into place.
Air gap created in-between the connecting contacts in the power cable connector, and the motherboard connector, created resistance.

Resistance creates heat. Burnt connector/s will result, and perhaps worse.
{Could also create a small power surge }

3) At one time Dell was a Proprietary computer manufacturer.
This means Dell wanted THEIR replacement parts used on THEIR computers.

If an aftermarket computer component is installed, Dell cannot warranty their computer.
Using THEIR parts in THEIR computers, Dell could.
However Dell computer users did not wish to pay the price of the Dell replacement parts.
The aftermarket parts were cheaper, of good quality, and readily available.

If we use a Power Supply for an example;

Dell had the motherboard manufacturer switch the socket holes around, in the Motherboard connector, for the main power cable.

They also had the Power Supply manufacturer switch the pins around, in the 24-pin ATX main power cable's connector, to match.

The aftermarket power supply manufacturer built the power cables, and connectors, to follow industry standards. Dell did not.

This means if you plug an aftermarket power supply's main power cable, into a Dell motherboard that was built proprietary, the motherboard usually fried. The only sign may be a burnt connector on the motherboard.

Could also have fried the Processor, Ram Memory, Harddrive, optical drive/s, and a graphics card, IF installed.

[ Looking at the Playtool link again, look at the photo to the far right.
See the different colored wires?
The color coding indicates what the wire carries as far as Voltage, or if it is a Ground wire.

1) Orange insulated wires = 3.3 Volts
2) Red wires = 5 Volts
3) Yellow wires = 12 Volts
(All are DC. In comparison two D cell flashlight batteries produce 3 Volts DC)

4) The Black wires are Ground wires

(The Green wire is the Soft Power On wire. Abbreviated as PS_ON)

The Orange, Red, and Yellow wires are power wires.
The Black wires are Ground wires.
Guess what happens if a 12 Volt wire is connected to a Ground?
(Instead of going to a 12 Volt connection)

Things start frying.

{To state connections in the main power cable connector, and it's respective connector on the motherboard, correctly;

Looking at the middle photo you see the connection end of the main power cable.
Plastic connector with individual plastic rectangular shapes, that have metal 'tubes' inside each of them.

The motherboard connector has socket holes to match the individual plastic rectangular shapes.
Inside the socket holes are metal pins. Contact pins.
The contact pins go inside the metal 'tubes'.

The metal 'tube' is a Molex Socket Terminal,

http://www.mouser.com/ProductDetail/Molex/36664-0002/?qs=sGAEpiMZZMvz8LftK4jerhl0r50z%252bUNRzFCdHbJqUTU%3d


4) IF the Power Supply, ( looking at it from the Back of the computer), has a rocker switch, or slide switch, to set the incoming AC power to 110 Volts, or 220 Volts;
And the power supply switch was set to 110, and plugged into 220 Volts,
the motherboard connector would fry.

Plus the Power Supply. May also of course include Processor, Ram Memory, Motherboard, Harddrive, optical drive/s, and graphics card IF installed.


Replace the connector? No
Could be;
A) Replace the Power Supply. Still no?
B) Replace the Motherboard. Still no?
C) Replace the Ram Memory. Still no?
D) Replace the Processor. Computer operates but no graphics?
E) Graphics card installed? Replace graphics card

Unless you can test each individual component, and the cost is not much less, or equal to a new computer, the obvious choice would be to purchase a new, or good used computer.

I replace my power supply for my E520 and its dose not turn on. It is a new replacement power supply for this model. I check alll the connections. It haas aa blinking amber light all time.


I would double check the connections to the main board. Some power supplies have two power connectors to the mother board, a 20 pin connector and a 4 pin connector. Sometimes the four pin connector is in a different location from the 20 pin on the board. Make sure both connectors a plugged in.

Make sure the connector for the power switch is plugged into the board. Dell's usually have all the wires for the front pane in one connector.

You should also unplug everything from the board except the power supply and front panel. There could be a hard device causing the board to hang up.

I have had power supplies die and short the main board. I hope that isn't the case here.

When turn on light turns yellow and would not boot


If the power light is steady amber- The computer is receiving electrical power, but an internal power problem might exist.
  • Ensure that the power cable is firmly inserted into both the power connector on the back of the computer and the electrical outlet.
  • Ensure that the voltage-selection switch is set to match the AC power at your location.
  • Ensure that the microprocessor power cable is securely connected to the system board.
  • Ensure that the power supply cables are securely connected to the system board
If the power light is blinking amber- A device might be malfunctioning or might be incorrectly installed.
  • Remove and then reinstall the memory modules (see "Memory" for module installation procedures).
  • Remove and then reinstall any cards (for installation procedures, see "Adding and Removing Parts" for your computer type).
  • Remove and then reinstall the video card, if applicable

Yeah I have seen switches fail a few times, its rare though, trace the wire back to your motherboard and disconnect the lead, then short the pins. If it comes on replace the switch, if it doesnt reset the bios via a the jumper and try again, disconnect the long ATX cable from the mother board and all power connectors from peripheral devices and on the Long ATX connector that was connected to the motherboard you will see a green wire, connect your mains to the power supply and short the green wire on the ATX connector with the black wire next to it, the power supply should fire up, if it doesnt try a new power lead and outlet, if it still does not fire up its your powersupply. If however you power supply does power up you should reconnect everything and try your power switch and shorting power switch pins on motherboard again, if the power supply does not come on then yor motherboard should be replaced.

Hi guys, just been given a dell optiplex gx520 to tinker with. when i plug it in, the power switch on the front flashes orange and the unit doesn't switch on. any ideas??


Did you open the case up and do a general inspection. Things to look for:

Is the CPU installed correctly and tight?
Is the RAM installed correctly? Are they the right type?
Is there another PCI cards? If so, make sure they are inserted tightly.
Are the power cables for the mother board attached correctly.
Look at all the unused power connectors for drives. Make sure the metal part are not touching anything conductive.

Good luck.
